Results of enclosure experiment. Results of a general linear model that tested for a difference in reproductive success (offspring sired) between high- and low-predation (LP) male guppies from the two separate trials of the enclosure experiment. A total of 56 male guppies, whose reproductive success ranged from 0 to 6, were included in the analysis. From this analysis, the least-squares mean number of offspring sired by high-predation and LP candidate sires was 1.65 and 0.68, respectively
